std::sub_match<BidirIt>::compare

1. Compares two sub_matches directly by comparing their underlying character sequences. Equivalent to str().compare(m.str()).

# Declarations

int compare( const sub_match& m ) const;

(since C++11)

int compare( const string_type& s ) const;

(since C++11)

int compare( const value_type* c ) const;

(since C++11)

# Parameters

• m: a reference to another sub_match
• s: a reference to a string to compare to
• c: a pointer to a null-terminated character sequence of the underlying value_type to compare to

# Return value

A value less than zero if this sub_match is less than the other character sequence, zero if the both underlying character sequences are equal, greater than zero if this sub_match is greater than the other character sequence.

# Notes

This function is infrequently used directly by application code. Instead, one of the non-member comparison operators is used.
